I have had my xbox (v1.0) for a while now and had it modded with the matrix modchip a while back. Everything has been fine, and i had the newest evox bios and ran avalaunch/xbmc/etc fine, although about a week ago something strange happened. I turned on my xbox and the red/green light came on, on the front of the xbox and the screen "Your Xbox Requires Service. Please call customer support" came up. I thought at first that it was the modchip unaligned, since it would get unaligned easily. So i matched it up, checked the modchip, green light comes on, on the modchip so everything seemed fine. Just to be sure i flashed the chip and verified that it was flashed with 2 different bioses (newest evox and cromwell). Both times, it will start up, goto the green X logo screen and where it should say (Mcrosoft/Xenium) or whatever, it then goes Red/Green flashing on the xbox and goes to the customer support screen....
The reason i dont think its the chip, is because i double checked the md5 checksums when it wrote to the chip, and later read it back and they all matched up... so i donno.
I'm out of ideas and its very frusterating... I have a good 100gb hd in there with a ton of backups and rom's that i dont want to lose.
anyone have an idea or suggestions?
